The stop in the opening position is on the one hand by meeting the ends of the hinge tab 1 on the legs of the link 15 and on the other hand by the leaf spring 16 given.

The longitudinal direction of the hinge is determined by roughening the contact surfaces, achieved here by cross-grooving a tongue 18; the latter is from beyond the U-legs extended web of the mounting bracket 3 formed. The edge-like edges appear to hit this grooved tongue a gap 19 which lies at the outer end of the hinge tab 2. This ending is of an extension 20 of the flap U-web is formed. In which can be seen from Fig. 1, bent position, it forms a conclusion that conceals the interior as well as a stop for the U-leg of the bearing block 3.

The adjustment of the door on the wall of the furniture body is achieved by a grub screw 21. This penetrates a threaded hole in the U-web of the hinge tab 2 uid occurs

The relocation of the flap 2 should always take place after the previous one Loosen the retaining screw 8, which must be tightened again after alignment, etc.

The hinge of Figure 3 has tabs 51 and 52 which are attached accordingly to the door and to the furniture body.

These hinge tabs 51 and 52 are connected to one another via articulated quadrangles. Two joint axes designated 61 and 62 are located on the hinge tab 51; a hinge axis 63 and a retaining pin 64 sit on the hinge tab The sides or legs of the quadrangle are on the one hand by the hinge tabs 51 and 52 themselves and on the other hand by a member 65 and a plane-wound spiral spring 66, the spiral-side end of which cannot be rotated on the retaining pin 64 is fixed. Nonetheless, the component, which looks like a stretched handlebar, pivots around a fictitious hinge point, the one here more or less with a plug 64 coincides.

The three hinge axes 61, 62 and 63 as well as the retaining pin are riveted to the hinge tabs 51 and 52 accordingly. They extend parallel to the supporting wall and furniture door. The hinge axes 61 and 62 are connected via the member 65 in the form of a leaf spring, the ends of which to form bearing eyes the hinge axes 61 and 63 are rolled up. The retaining pin is not round in cross section, preferably square and for the purpose of its non-rotation in this square contour adapted holes in the legs of the in the form an inverted U shaped hinge tab attached. To avoid a rotational movement of the spring 66 on the Holding pin 64 this end is rolled up to form a polygonal storage cavity around the holding pin 64; the other end of the spiral spring 66 is placed around the journal 62 to form a bearing eye.

The member 52 is seen in cross section, essentially U-shaped and by means of a bearing block 53 with the Furniture body connected. This bearing block 53, which

cut tabs in the upper leg of this fastening bracket 53. The tabs are achieved by angle cuts 74. The angle of intersection is 90 degrees, with the one angle leg entering from the edge transversely to the longitudinal direction of the lug and the other, adjoining it, runs in the longitudinal direction of the same.

The tongues 73 obtained in this way are bent in the direction of the furniture wall in such a way that they are located opposite the path of the projecting tongues 59 of the hinge tab 52. The mounting of the hinge tab 59 on the mounting bracket 53 is carried out by sliding the hinge nierlappens 52 onto the narrow sides of the folded-back leg of the mounting bracket 53, the guidance by the sliding guide projections 58 is ensured. During this sliding movement, the tongues are at a distance from the Höbelwand, due to their flexibility or deformability when passing the tongues 59 effective clip lock, the definition of the assumed position is secured by the screw 75. The parts 52 and 53 are captively tied to one another.

When the hinge tab 52 is in the desired position in relation to the fastening bracket 53, The final fixing is brought about by the screw 55, which is also the angle tip of the protruding Brings tongues 59 into contact with the bottom of the grooves and the lower end of the same projecting tongues 59 with the bottom of the grooves 71.

According to another embodiment (Fig. 6) of the hinge tab 52 whose legs are each one by undulating folds, dispensing with cut-out windows obtained sliding guide 108 is integrally formed, each of which receives a narrow side of the fastening bracket 53. Only the lower support leg is achieved by cutting free a corresponding flap.

According to another embodiment (Fig. 9) of the fastening lugs 53, the upper leg is angled transversely in such a way that this, seen in cross section, has the shape of an inverted one U has, which is between the U-legs of the

409851/0269

15 404/405 May 13, 1974

Hinge tab 52 leads. The definition of the projecting tongue 59 of the hinge tab 52 is made by the grooves of the upper and 122 of the lower leg of the mounting bracket brought about. After this is the turn of the hairpin-like bent lug made from a leaf spring can no longer be moved forwards or backwards.

According to another embodiment (Fig. 10) of the fastening bracket 53, the upper leg is angled transversely in such a way that it is U-shaped when viewed in cross section profiled and guided between the U-legs of the hinge tab 52; this mounting bracket allows the use of fastening screws of the same length.

In the embodiment according to FIG. 11, leaf spring and One-piece hinge tabs. A correspondingly elastic or flexible base material is used for the hinge tab or one which subsequently has partial hardening adapted to the purpose of the spring 16 forming

409851/0269

15 404/405 May 13, 1974

Section allows. The rest of the configuration corresponds approximately to that shown in FIG. This embodiment has the advantage that assembly means and devices for fixing the leaf spring 16, that is to say the rivet 14 here, are dispensed with can be.

Finally, it is also possible to achieve a likewise more advantageous embodiment of the spring 16 (FIG. 12); this way Spring 66, punched out in the desired outline shape before rolling, has one on each of the two narrow sides Tongue 661 protruding over the width of the spring. This is rectangular and is made by an opening in the hinge tab 52 added. This configuration allows the spring 66 to be fixed on the hinge tab 52 merely embracing, which makes a retaining pin 64 with a square cross-section practically unnecessary.

The use of such fastening lugs is of considerable advantage: they allow the expedition of furniture in dismantled state as well as a later, quickly and precisely feasible assembly of the doors, flaps, etc. This
